The behavior of temporary sales in a macroeconomic context

Nós investigamos promoções temporárias usando uma base de dados detalhada de 13 anos sobre preços ao consumidor no Brasil, com cotações de preços coletadas decendialmente. Nós encontramos forte evidências da existência de relação entre a frequência e tamanho de promoções e as variáveis macroeconômicas. A crença comum na literatura de que promoções não reagem a mudanças nas variáveis macroeconômicas pode ser devido a baixa volatilidade do cenário macro- econômico nos países analisados até o presente momento.

Estudo sobre comportamentos de cidadania organizacional em organizações temporárias

Esta dissertação buscou aumentar os conhecimentos sobre os comportamentos de cidadania organizacional (CCO), que são ações informais de trabalhadores que beneficiam a empresa, através da análise de como estes comportamentos se manifestam em empresas que adotam estruturas temporárias para realização de suas atividades, ou seja, estruturas organizacionais temporárias (EOT). Nos estudos desenvolvidos, um modelo representativo das relações dos constructos referentes aos antecedentes cognitivos e afetivos com as dimensões que compõem os CCO foi proposto e as respectivas relações foram testadas. O estudo contou com a participação de 86 profissionais que trabalham em empresas com características equivalentes às EOT e permitiu avançar no conhecimento a respeito deste tipo de organização que carece de estudos empíricos a respeito. Estes profissionais responderam a um instrumento contendo 7 escalas de medidas das variáveis constituintes do modelo, desenvolvidas e validadas por outros autores. Os dados foram tratados por meio de análises fatoriais e por modelagem de equações estruturais. Os resultados mostraram que os CCO são significativos em EOT, apesar da ideia de temporalidade e das características referentes aos profissionais e tipo de atividades presentes (alta especificidade do produto e alta qualificação dos profissionais) sugerir inicialmente o contrário. Além disso, os resultados confirmaram que as cognições sobre a organização constituem um fator preponderante na formação dos afetos que os profissionais nutrem pela empresa e estes, por sua vez, mostraram possuir relação significativa sobre as ações que correspondem aos CCO.

From public to private : the performance of former public workers in the Brazilian labor market

This paper analyzes the placement in the private sector of a subset of Brazilian public-sector employees. This group left public employment in the mid-1990’s through a voluntary severance program. This paper contrasts their earnings before and after quitting the public sector, and compares both sets of wages to public and private sector earnings for similar workers. We find that participants in this voluntary severance program suffered a significant reduction in average earnings wage and an increase in earnings dispersion. We test whether the reduction in average earnings and the increase in earnings dispersion is the expected outcome once one controls for observed characteristics, by means of counterfactual simulations. Several methods of controlling for observed characteristics (parametric and non-parametrically) are used for robustness. The results indicate that this group of workers was paid at levels below what would be expected given their embodied observable characteristics.

Temporary exchange rate-based stabilization programs under asset market segmentation

This paper analyses the welfare consequences of temporary exchange rate-based stabilization programs. Differently than previous papers, however, here we assume that only a fraction of households participates in asset market transactions. With this asset market segmentation assumption, the effects of temporary programs on welfare may change drastically. Households with access to the bonds market are able to protect themselves better from the changes in the inflation rate – although at the cost of a distortion in their consumption path. As a consequence, they may decrease their inflation tax burden – which would increase for the other group of households. By the other side, when these agents that lack the access to the asset markets are credit constrained, they may welcome the program, since the government Is temporally reducing the inflation tax they have to pay. The temporary program could end up benefiting both groups, what could help to understand their popularity.

The influence of lifestyle and gender on sickness absence in brazilian workers

Background: Despite an increasing body of knowledge concerning gender and lifestyle factors as determinants of sickness absence in well-developed countries, the relationship between these variables has not been elucidated in emerging economic power countries, where the burden of non-communicable diseases is particularly high. This study aimed to analyze the relationships among lifestyle-related factors and sick leave and to examine whether gender differences in sickness absence can be explained by differences in socio-demographic, work and lifestyle-related factors among Brazilian workers. Methods: In this longitudinal study with a one year follow-up among 2.150 employees of a Brazilian airline company, sick leave was the primary outcome of interest. Independent variables collected by interview at enrolment in the study were gender, age, educational level, type of work, stress, and lifestyle-related factors (body mass index, physical activity and smoking). In addition, the risk for coronary heart disease was determined based on measurement of blood pressure, total cholesterol and glucose levels. The total number of days on sick leave during 12 months follow-up was available from the company register. Logistic regression analysis was used to determine the influence of socio-demographic, type of work and lifestyle-related factors on sick leave. Results: Younger employees, those with lower educational level, those who worked as air crew members and those with higher levels of stress were more likely to have sick leave. Body mass index and level of physical activity were not associated with sick leave. After adjustment by socio-demographic variables, increased odds for 10 or more days of sick leave were found in smokers (OR = 1.51, CI = 1.05-2.17), and ex-smokers (OR = 1.45, CI = 1.01-2.10). Women were more likely to have 10 or more days of sick leave. Gender differences were reduced mainly when adjusted for type of work (15%) and educational level (7%). Conclusions: The higher occurrence of sick leave among women than among men was partly explained by type of work and educational level. Our results suggest that type of work, a stressful life, and smoking are important targets for health promotion in this study population
